Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Tracing the Evolution of SMBHs and Stellar Objects in Galaxy Mergers: A Multi-mass Direct N-body Model
星系合并 SMBH 恒星物体演化 多质量 直接N体模型
2023/11/13
By using direct N-body numerical simulations, we model the dynamical coevolution of two supermassive black holes (SMBHs) and the surrounding stars in merging galaxies. In order to investigate how diff...
THE PROPERTIES OF X-RAY LUMINOUS YOUNG STELLAR OBJECTS IN THE NGC 1333 AND SERPENS EMBEDDED CLUSTERS
new Chandra X-ray data NGC 1333
2014/12/22
We present new Chandra X-ray data of the NGC 1333 embedded cluster and combine these data with existing Chandra data, Spitzer photometry, and ground-based spectroscopy of both the NGC 1333 and Serpens...
Emission line diagnostics of magnetospheric accretion in young stellar objects
Line emission Stars Accretion Star formation Formation of the accretion flow Stars Magnetic layer
2014/12/9
This thesis seeks to explain the nature of line emission observed in young stellar objects, and to use the lines as diagnostics of the accretion process that is central to star formation. We maintain ...
Multiwavelength study of parsec scale outflows associated with low mass young stellar objects
Arrow flow Low quality of the original star formation Optical observation star
2014/12/9
A multi-wavelength, multi-telescope observational study of recently discovered parsec-scale Herbig-Haro flows associated with the earliest stages of low mass protostellar formation is presented. Impro...
A Correlation Between Surface Densities of Young Stellar Objects and Gas in Eight Nearby Molecular Clouds
Stellar Objects Gas Nearby Molecular Clouds
2011/9/28
We report the discovery and characterization of a power law correlation between the local surface densities of Spitzer-identified, dusty young stellar objects and the column density of gas (as traced ...
Ice chemistry in massive Young Stellar Objects: the role of metallicity
astrochemistry – circumstellar matter – galaxies individual (LMC, SMC) –Magellanic Clouds – stars formation – stars: protostars
2010/11/15
We present the comparison of the three most important ice constituents (water, CO and CO2)
in the envelopes of massive Young Stellar Objects (YSOs), in environments of differentmetallicities:the Gala...
The interactions of winds from massive young stellar objects
interactions of winds massive young stellar objects
2010/11/10
The supersonic stellar and disk winds possessed by massive young stellar objects will produce
shocks when they collide against the interior of a pre-existing bipolar cavity (resulting from an earlier...
